Tecal Series of Dri-Block® CalibratorsThe Tecal Block Calibrator series are used as portable temperature calibrators in a wide variety of industries for checking the calibration of thermocouples, RTDs and liquid filled sensors.

The checking of temperature is vital in many industrial processes – engines, machines, boilers,

pumps, storage rooms, air conditioners and compressors used in power stations, chemical plants,

refineries, off-shore platforms, ships, steel works and instrument companies which are all typical

applications for uses of this type of equipment.

The Tecal series comes in three different models offering from simple, reliable and portable temperature calibration and also for applications where greater flexibility is required.

The Tecal ‘F’ units are lightweight portable units in 2 versions with or without RS-232.

The Tecal ‘S’ units are designed for Laboratory use and include RS-232.

The Tecal ‘H’ units have programming facilities with a switch test function and RS-232.

With the Tecal ‘S’ and ‘F’ models calibration is simple, quick and easy.

1. Select the temperature scale required (°C or °F) and calibration temperature on the LED display.

2. Place the insert into the hole in the block.

3. Place the sensor under test into the insert.

4. Connect the sensor to reading device (DVM, Digital Thermometer or sensor controlling circuit etc.)

5. Allow the block to stabilise for at least 10 minutes once it has reached the desired temperature.

6. Compare the temperature reading of the external thermometer with the reading on the Tecal LED display.

7. Repeat the above steps for all calibration temperatures until the calibration is complete.

The Tecal ‘H’ range allows greater flexibility where several calibration programs may need to be carried out in the field.

1. The ‘H’ range is fitted with a 4 line by 20 character LCD and an 8 button keypad for creating and using calibration programs (setting temperature, ramp rate and holding time) and storing data at each temperature.

2. The LCD and keypad allow the user to configure the calibrator for:

A normal calibration of temperature probes (analogous to the ‘S’ range).

A switch test input for monitoring hydraulic thermostats, including the ability to pause at the temperature where switching occurs (very useful when the temperature for switch changeover is not known).

A calibration using the User Probe Interface (UPI), (see page 12) which allows storage of both the block temperature and the reading of the test sensor which is connected to the UPI.

The Tecal ‘H’, ‘S’ and selected Tecal ‘F’ models have an RS-232 interface for data and program transfer or real time control using Techne Works (see page 11).

The ‘S’ and ‘F’ models require the computer to be continuously connected to the Tecal calibrator when using Techne Works.

On the other hand, the ‘H’ range can calibrate probes independently of the computer and at the end of the day, the user can download the test results from the Tecal calibrator to the computer to print out the appropriate calibration certificate(s).

A set of software commands is available allowing third party software applications to be devel-oped. For further details, please contact the Techne Sales Department.

All Tecal calibrators have a large heater block (aluminium for the Tecal 140 & 425 models, and aluminium/bronze for the Tecal 650) which provides optimum uniformity and stability. This heater block can accommodate large multi-hole inserts allowing calibration of several probes at one time.

Special inserts are available upon request.

All Techne units are designed and manufactured to BS EN 1S0 9001: 1994 and carry the CE mark.

All Techne equipment conforms to the EMC and Low Voltage Directives.

Calibrate with confidence using the Tecal “Field” Range of Dri-Block CalibratorsA new range of lightweight dry-block thermal calibrators that operate from 45°C below ambient up to 650°C has been developed by Techne for convenient use in the field.

The three models in the new Tecal F range incorporate the precision control system used on Techne’s Tecal H and S models to provide excellent reliability and accuracy, with a number of improvements such as an enhanced display resolution of 0.01°C and faster heating and cooling rates.

The Tecal 140F operates between 45°C below ambient (typically -20°C) and 140°C with a temperature accuracy of ±0.3°C and a temperature uniformity of ±0.2°C. Heating time to 100°C is five minutes.

All the models are offered with or without RS-232 communications and can be used with a wide range of inserts to suit different probe sizes. Automatic fan cooling is standard, with accelerated cooling probes also available.

Tecal S and H range Dri-Block CalibratorThis range of temperature calibrators is ideal for calibrating temperature sensors used in the food and pharmaceutical industries in addition to calibrating any sensors used in the temperature range outlined in the specifications below. S Version: Set required Temperature and Calibrate

H Version: Set required Temperature and Calibrate; also programmable for switch test and ramp rate etc.

Tecal 140S/H The Tecal 140S provides a complete system for calibrating most types of thermal sensors used in the temperature range of -40°C to 140°C which includes “K” type thermocouples commonly used in the food industries, cold storage rooms and environmental monitoring systems.

Where automation in both the field and laboratory are required, the combination of the Tecal 140H with the UPI (see page 13) saves time and money. The user can set the program and leave the unit to calibrate the probes, automatically storing the results in memory. This allows the user to attend to other tasks and when convenient download the results to a computer to print the calibration certificate.

Using advanced peltier technology and state-of-the-art mechanical and electrical components, these calibrators can rapidly cover the complete temperature range where speed is of the essence without loss of accuracy or stability. The heater block with a defined measuring zone of 50mm from the bottom of the block allows for different length/active area sensors. Although the quoted accuracy and stability is ±0 .3°C & ±0.05°C respectively, one can often achieve an accuracy of ±0.1°C and a stability of ±0.02°C with high class RTDs and thermocouples.

The CH-5 Chiller UnitThe CH-5 Chiller Unit is designed for use in conjunction with the TECAL 140 H&S Calibrators to achieve calibration temperatures down to -40°C. Chilled water pumped through the Heatsinks on the Tecal 140 units to allow the Tecal to reach -40°C.

In normal ambient temperatures of up to 20°C the minimum temperature obtainable with the TECAL 140 models is 45°C below ambient; by artificially cooling the heatsink of the units with water from the chiller -40°C can be obtained.

The unit is designed to run on distilled or deionised water.

The CH-5 can also be used to pass cooling water through the cooling coil on the Calibration Baths (LCB) and Cooling Probe (FDB00CP); minimum temperature +10°C.

liquid temperature calibration baths

Water BathsA comprehensive range of temperature controlled water baths are available from Techne. Twenty different water bath combinations allow the use of accurate temperatures from -40°C up to 200°C; ensuring a solution for most laboratory applications. First select the unheated stainless steel bath (see page 23) which has the appropriate volume for the application, for example B-26 which has a volume of 26 litres.

Then add a thermoregulator (see page 24-25) which is suitable for the required temperature range, for example the TE-10D Tempette is a digital thermoregulator for temperatures between -40°C and 120°C.

Select any accessories that are required, for example; both gabled and flat lids are available for all bath sizes. Gabled lids allow particularly tall tubes to be accommodated.

If sub-ambient temperatures are required it is necessary to add a cooling mechanism to the bath. Techne recommends the use of a dip or flow cooler for temperatures down to -35°C. For example the RU-200 can lower temperatures down to -20°C. It is also possible to use the cooling coil with a water supply for temperatures from 5°C above the water temperature to ambient.

To assemble the complete system shown opposite the following products are required:

Choice of liquidsSome liquids can be hazardous when used in thermostatic baths. The user should ensure that due regard is paid to the flash-point and other characteristics of the chosen liquid. This table does not represent the recommendations of Techne but may be of assistance to the user in making an initial selection.

Liquid Bath AccessoriesCooling coil

Connects to the mains water supply; the water being circulated through the coil should be at least 5°C cooler than the set of the bath temperature. (Fits to any TE or TU unit).

Flat and gabled lids

Manufactured of stainless steel and available to fit all sizes of temperature controlled bath to help prevent evaporation losses. Gabled lids provide extra working headroom within the bath.

Adjustable trays

Supported by a ball chain and clip the stainless steel trays can be used to alter the depth of the bath.

Polypropylene spheres

A ball blanket is an effective way of reducing evaporation and loss of heat from a water bath. It acts as effectively as a lid, whilst providing instant access to the bath. The 25mm diameter spheres are supplied in packs of 250.

precision temperature fluidised sand baths

Precision Temperature Fluidised Sand Baths With more than 50 years experience in the field of temperature control, Techne has established itself as a world leader in the design and manufacture of equipment used for both laboratory and on-site temperature calibration, providing the calibration engineer with a precise dynamic stable temperature source.

Exceptional temperature stability and uniformity also make Techne fluidised baths the ideal choice for critical heat treatment procedures.

Pioneers in the development of fluidised bath technology, Techne have a wide range of products capable of covering the temperature range –100°C to 1100°C.

The fluidised bath is constructed from a container filled with dry inert particles of aluminium oxide. When a gas flow is passed through the particles via a porous distribution plate, the particles are separated and suspended in the gas flow and give the appearance of a boiling liquid.

Apart from circulating and flowing like a liquid, fluidised particles exhibit excellent heat transfer characteristics. When fluidised particles are heated, heat is distributed quickly and evenly throughout the bath and transferred rapidly to objects submerged in the bath. The bath temperature can be adjusted easily to the point at which you wish to calibrate or carry out a heat treatment application.

Within the temperature range of the unit the aluminium oxide does not melt or reach boiling point. Therefore, solidification which takes place in salt baths and fumes from hot oil baths are eliminated.

Fluidised baths are dry and inert, making the medium a safe and clean alternative to conventional liquid systems and salt baths.

Techne fluidised baths are used in materials and component quality control, instrument calibration laboratories and thermal processing production departments. They provide rapid heat transfer and precise temperature control to calibrate and maintain temperature sensitive instruments efficiently and safely.

SBL RangeThe SBL range of Fluidised Baths offer a safer alternative to the dangers associated with high temperature oil and salt baths.

These units are designed to be bench or floor standing and only require an electrical and air supply for operation. Air passes through the mass of the aluminium oxide (Alundum) particles via a porous plate in the base of the unit separating the individual particles and suspending them in free air, giving the properties of a liquid bath. Heaters are fitted within the bath which allow temperatures of up to 600°C to be maintained. All the SBL range units have a stainless steel inner container insulated from the outer wall and a safety air pressure switch in the event of loss of air and also a thermal cut-out. A range of accessories are available.

All SBL units can have their temperature accuracy (and setability) improved by fitting the optional TC-8D temperature control unit (see page 38) which will maintain the temperature to within ±0.3°C.

SBL-1With a temperature range of up to 350°C this unit covers a wide range of applications.

Simple to operate and maintenance free the SBL-1 Fluidised Bath provides a uniform and stable heat source and will control the temperature to within ±1°C.

The SBL-1 has a working volume of 228mm diameter and 120mm deep. The unit is fitted as standard with an energy regulator to set and control the temperature. Selector switches are used to add or reduce power when required with neons illuminating when power is applied to each of the two heating elements.

SBL-2For temperatures up to 600°C the SBL-2 Fluidised Bath will maintain temperature to within ±1°C. The working volume of the unit is 228mm diameter and 140mm deep. Three 1kW heaters give a heat up time from ambient to 600°C of approximately 100 minutes. (All the SBL range of units have a pocket in the fluidised bath that will accept a 5mm diameter control thermocouple.)

SBL-2DThis extra depth fluidised bath is based on the SBL-2 but with an increased working depth of 350mm. Four 1kW heaters give a heat up time from ambient to 600°C of approximately 100 minutes.

TC-8D & RS-232Designed to improve the temperature stability and temperature setting accuracies the TC-8D is compatible with all of the SBL series of fluidised baths.

The TC-8D is a self contained unit and is supplied complete with a chromel/alumel Type K thermocouple which fits into the sheath supplied with the SBL baths.

The unit has digital set point of bath temperature on an LED display with PID control.

A TC-8D with RS-232 communication is also available for use with our custom iTools software for programming ramps, dwells and hold at up to 10 temperature set points.

FB-08 RangeThe FB-08 series are precision fluidised baths with exceptional temperature stability and uniformity making them the ideal choice for critical temperature calibration and heat treatment processes. The characteristics of the FB-08 series offer excellent thermal uniformity and heat transfer to make them a useful tool in the calibration and testing of a very wide range of temperature sensors.

These FB-08 and FB-08C Fluidised sand baths have become the market standard for carrying out shape setting (heat treatment processing) on Nitinol wire in a precisely controlled and uniform manner. Platinum/tungsten products are now also being processed successfully. The Fluidised baths offer lower running costs and are much safer to use than the alternative salt baths and give much better results than conventional ovens. These products have excellent temperature uniformity and offer fast temperature immersions as the fluidised alumina behaves like a liquid. The typical processing time is typically 2-3 minutes per item for immersion in the bath which is then followed by quenching in a cold fluid.

The unit is suitable for many other applications including thermal testing of sensitive components such as semiconductor devices, wire product testing, delicate transducers and they may also be used as a constant temperature environment for chemical reactions.Because the fluidised bed is a fine dry powder, it does not have surface tension effects of liquid baths, and does not wet any objects immersed in it. The electrical insulating properties of the alumina used in the FB-08 series are not affected by fluidisation, making it possible to conduct electrical measurements on immersed objects such as assembled printed circuit boards.

Temperature stability, as good as ±0.2°C

Controls for temperature and fluidising air flow are mounted on a recessed panel on the front of the unit together with on-off switches for the power supply and the dust extraction system.The inner container is well insulated and the outer case is vented so that it remains safe and cool to the touch even when the bath is operating at its maximum temperature. The inner container is filled from the top with alumina. When fluidised the alumina is heated by the four immersion heaters close to the inner container outer wall with the control thermocouple giving excellent temperature control.

The heater elements are protected (by a pressure switch operated by the fluidising air) from excessive surface temperatures and the power supply is removed if the air supply to the unit is disrupted. The unit also has an over-temperature cut-out fitted to protect the heating elements if a fault with the control system occurs. Air supplied to the unit passes through two filters and a pressure regulator to remove any oil and moisture and to set the correct pressure for the cyclone extraction system and for optimum fluidisation.

The fluidising air passes through a flowmeter and then to a plenum chamber from which it is distributed evenly across the inner container.

Dust extraction is carried out by ambient air being drawn down past the probe plate and through a peripheral slot around the top edge of the inner container. It then passes through a cyclone to separate and remove any alumina particles which are collected in a glass collection jar and then passes through the exhaust filter.

Entrained alumina removed by the cyclone and collected in the collection jar, which is accessible from the front of the unit, can be re-used and simply emptied back into the bath.

Sensor calibration or precision heat treatment is simple and precise with the FB-08 series fluidised baths.

Set the bath to the required temperature and air flow level (on manual units).

Suspend the sensor to be tested in the bath (using the probe plate supplied or basket) in the working area and allow the bath to stabilise for a short period.

Calibration or heat treatment can now be carried out using either a certificated standard (Comparison method) or the readout from the FB-08 control unit (direct method).

Other inert gasses can be used for special applications provided appropriate precautions are taken.

FB-08, Fluidised BathThe FB-08 series Fluidised Baths are precision baths with exceptional temperature stability and uniformity and are a safe and clean alternative to conventional liquid systems and salt baths. The fumes from oil and salt baths and also the dangers in placing components with moisture on into the bath are eliminated.

In operation, first set the flow of fluidising air by means of the control valve on the flowmeter. The setting will vary depending on the operating temperature; at higher temperatures a lower flow rate is required for good fluidisation. Select the required operating temperature on the temperature controller. The digital display indicates the set point value and the actual bath temperature. Sensors for calibration should be suspended as close as possible to the centre of the working area or for increased uniformity by using a probe holder.

This model is specially designed for low temperature operation down to –100°C and is also capable of operating up to +200°C. The unit includes all of the special features listed for Model FB-08 fluidised bath. The method of operation is similar to Model FB-08 except that it has provision for connection to a LN2 supply and is fitted with an air drying system (mounted on the back of the unit). The air drier is required to prevent moisture in the fluidising air being intro-duced into the chilled fluidised bed thus preventing the alumina from fluidising. The LN2 supply is selected with a valve on the front of the unit. It is regulated by a flowmeter which controls the flow of nitrogen gas into the bath. The gas is exhausted from a connection on the rear of the unit and should be ducted to a well ventilated area.

At low temperatures the top opening of the bed should be completely closed, using the blanking plate provided, to avoid warm ambient air being drawn into the bed. The LN2 flows through a helical tube around the outside of the cylindrical stainless steel containing the fluidised bed. Temperature is controlled by a platinum resistance thermometer and is indicated on a large digital display. The entire system is completely self-contained. All that is required is a supply of liquid nitrogen and air, an electrical supply and you have a dry, safe calibration bath working down to –100°C with considerable precision. Sensors for calibration should be suspended as close as pos-sible to the centre of the working area or, for increased uniformity placed in a probe holder.

FB-08C, Fluidised BathThe FB-08C has been designed to allow for calibration of thermal sensors over the temperature range 50°C to 700°C with minimum supervision and works in conjunction with a supervisory computer via an RS232 interface. Basic control programmes are set by the operator allowing for the control of set temperature, incremental temperature steps, dwell times and control of dead bed state.

Temperature range 50°C to 700°C

Temperature stability, as good as ±0.01°C


PID temperature control

Multiple set points and dwell times can be set by computer/programmable controller

This model is specially designed to allow the operating temperature of the fluidised bath to be adjusted from a remote source while the bath is unsupervised. An automatic fluidising air control system is fitted which adjusts the air flow rate accordingly to suit the set temperature of the bath.

This automatic air feature is controlled by a control system which switches five solenoid valves.These valves are opened and closed in various combinations, providing eighteen air flow rates corresponding to eighteen different temperatures throughout the operating range. Where an ultra stable temperature condition is required a “dead bed” state can be programmed into the control system. During this “dead bed” condition the air and electrical supply to the fluidised bed are switched off. For a period of up to 6 minutes the fluidised bed becomes an isothermal mass without heat input and very low heat loss. Under these conditions the stability at the centre of the aluminium oxide is ±0.01°C over the range of the unit.

A probe holder is available as an accessory (see page 42) that enhances the thermal conditions (control stability and uniformity) of the temperature zone within the baths (It is manufactured to special order to suit sensors under test).

The air flow to the fluidised thermal mass is automatically adjusted in order to maintain optimum isothermal conditions throughout the temperature range of the unit. Variable ramp rates of heating can be programmed with the Eurotherm 2408 controller or via a PC using the optional software package iTools.

BFS high temperature calibration bath Temperature range 200°C to 1100°C


The BFS is designed for applications requiring a constant high temperature source for calibration. The BFS has a hinged lid and a cylindrical bath 218mm in diameter and 254mm deep. Substantial fire brick insulation is incorporated within the outer container and the lid.

Standard equipment includes a separate air supply control unit which incorporates two flowme-ters for monitoring the air supply and a charge of fluidising medium (aluminium oxide) and air diffuser (zirconium oxide).

The inner container of the BFS is filled with two layers of fine granular particles. The lower layer (zirconium oxide) is denser than the upper layer (aluminium oxide) and does not fluidise but instead acts as a heat insulator. The inner container of the BFS is divided into inner and outer fluidised sections. Each area has a separate air supply which must be oil, water and dust free.

The air supply may be monitored on flowmeters in the air flow unit. Air supplies are adjustable to obtain uniform fluidisation in both sections of the bath. Heaters are mounted in firebrick insula-tion between the inner and outer container; heat is radiated inwards to the fluidised bath.

An air extraction tube is located in a horizontal position in the side of the bath just below the hinge on the lid. When the lid is closed, dust created by the bath’s operation can be withdrawn by connection to an extraction duct or fan. The dust can also be trapped in a small tank of water.

TC-5 Temperature ControllerThe TC-5 supplied with the BFS uses a chromel/alumel thermocouple, supplied as standard, which mounts onto the back of the BFS and fits into the pocket of the inner container. The TC-5 is fitted to the air flow control unit. The TC-5 uses an Eurotherm controller for setting the tem-perature in the fluidised bath and will control and indicate the bath temperature.

Advance PID controller giving set and actual bath temperature read out. Control algorithm gives stable ‘straight line’ control with self and adaptive tuning.
